进行了基于横摆角速度变逻辑门限值的车辆稳定性控制策略研究,分析该策略的Matlab/Simulink仿真结果,开发了基于DSP的车辆稳定性控制器ECU,实现该控制策略。实车场地试验表明,基于该控制策略的控制器实用且有效,能够大大提高汽车在极限状态下曲线行驶的车辆稳定性。
A vehicle stability control strategy based on the variable-threshold of yaw rate is studied, and the results of Matlab/Simulink simulation on the strategy are analyzed. A DSP-based ECU of vehicle stability controller is developed for implementing the strategy. The vehicle field test shows that the controller based on proposed strategy is practical and effective, it can greatly improve the vehicle stability when running on curved road under extreme conditions.
